I mean, the non-null precondition does actually come from C itself, so that is where it'd need to be fixed. I think it's also demonstrably a problem on the spec side, seeing as it's inconsistent with how anyone anywhere writes C code. (Chrome for Linux currently cannot even compile with the relevant UBSan bit turned on because some tool used during the build computes `(T*)NULL + 0`.) But, fair enough, I will reword the commit message. :)
